SELF-DISCHARGING GAR.

Specification of Letters Patent. Patented J an, 17, 1922.

Application filed February 14, 1921. Serial No. 444,863.

T 0 all whom it may concern:

Be it known that I, CARL Sonfirz, residing at Essen, Germany, a citizen of the German Republic, have invented a certain new and useful Improvement in Self-Discharging Cars, (for which I have filed an application in Germany, July 16, 1919,) of which the following is a specification.

This invention relates to selfdischarging cars having stationar end walls and a flat, tiltable bottom, and 1n which the side wall located on the discharge side is suspended by a link, whereas the opposite side wall, which is articulated to the bottom is adapted to shift toward the discharge side when the bottom comes to be tilted. The object of the invention is to provide for cars of this kind an arrangement which will enable the discharging operation to be satisfactorily carried out even in the event of the goods lodged in the middle of the car when loaded considerably protruding beyond the upper edge of the loading room.

The invention will be further described with reference to the accompanying draw ing which illustrates by way of example, one embodiment of the subject matter of the present invention and in which:

Fig. 1 is an end view of the car ready for loading and Fig. 2 is a like view of the car when in the discharging position.

Referring to the drawing, the two end wells A are rigidly fixed to the underframe A of the car. The bottom B is mounted to rotate by aid of an axis 6 on the underframe A; the said axis being located on the side of the car remote from the discharging side. The side wall C, disposed on the same side as the axis 6 is articulated to the bottom B and is guided in its motion in the known manner by means of rods D, engaging the upper edge of said side wall, in such wise that during the discharge action theside wall G will remain substantially parallel to itself (Fig. 2.) The other side wall, E, is suspended at its upper edge on each side by means of a pin F in one arm G of a twoarmed lever which is fixed to the adjacent end wall A The opposite arm G of this lever is united by means of a connecting rod H to an extension, disposed toward the discharge side, of the rod D loc ted on the same end wall of the car. The side wall E is provided at its lower edge with a plurality of claws e by aid of which it .is enabled to engage the underside of the bottom B- and to fix it in the position ready for loading. A connecting rod J, belonging to a crank mechanism operated by means of a hand-crank K, engages the side wall E; the said crank- WVhen the car is to be discharged, thecrank K is turned in suchwise that the side wall E will swing outward about the axis of the pins F, the claws e at the same time releasing the bottom B. Then, the weight of the goods causes'the bottom B to tilt in the direction indicated by the arrow 00 (Fig. 1) owing to the "fact that the axis 6 is mounted laterally, the sidewall C, articulated to the bottom B, hereby being raised and displaced substantially parallel to itself toward the discharge side. Simultaneously, the pins F arranged on either end of the car and by which the side Wall E is suspended, are shifted outward by the lever mechanism D H G G, in positive dependency upon the tilting motion effected by the bottom B.

The car having been discharged, the movable parts B, C, D, H, G, G and F thereof are swung back into their initial positions,- whereupon, by returning the crank K and therewith the connecting rod J, the side wall E is drawn with its lower edge toward the car again, so that the claws e re-engage the bottom B and thus close the car.

By the hereinbefore described arran eof the loading room, there will be created no liability of the goods, While discharging,

cloggingup the spacebetweerr the bottom and the upper edge of the side Wall E.

I claim:

1. A self-discharging car of the class described comprising a pivoted bottom, stationary end walls, a side wall hingedly connected to said bottom and adapted to move toward the discharge side of the car during a tilting motion of the bottom, a wall disposedon the discharge side of the car, means for supporting this last named wall whereby it may be moved outwardly duringa tilting motion of the bottom and in positive dependency upon this motion.

2. A self-discharging car of the class described comprising a tiltable bottom, a pair of stationary end Walls, a side wall articulated to said bottom andadapted to move towards the dischargeside of said car during aitilting motion of the bottom, a second sidewall for the discharge side of said car, levers supportingsaid side wall and means rotating said levers in a direction to move outward said side Wall away from said car during a tilting motion of said bottom.

3i A self-dischargingcar ot' the class described comprising a tilt-able bottom, a pair of stationary end walls, a side Wall articulated: to said bottom and adapted to move to- Wards the discharge side of said car during a tilting motion of the bottom, a second side Wall for the discharge side of said car, double armed levers supporting said side wall and means connecting said double armed levers to the first mentioned side wall whereby said second side Wall will be moved outward away from said car during a tilting motion of said bottom.

4. A self-discharging car of the class described comprising an underframe, a flat tiltable bottom pivotally mounted on said under frame on the side thereof removed from the discharge side of said car, a side wall articulated to said bottom and adapted to be displaced substantially parallel to itself toward the discharge side of said car during a tilting motion of the bottom, a second side Wall for the discharge side of said tiltable bottom, a hand crank and means connecting said hand crank to said second slde wall for causing it to disengage said tiltable bottom whereby said bottom may tilt and the connection between said firstand second side walls cause said second side Wall to swing free of said car.

The foregoing specification signed at Essen, Germany, this 15th day of November,
